UNLoAnINe RACK.

Application led November 7, 1921. Serialy No. 513,233.

T o all whom it may concern Be it known that I, AUSTIN L. WnRTz, a citizen of the United States, and a resident of the city of Dubuque, in the county of Dubuque and State of Iowa, have invented certain new and useful Improvements in an Unloading Rack; and I do hereby declare that the following is a full, clear, and exact' description of the saine, reference being had to the accompanying drawings, and to the numerals of` reference marked thereon,

which form a' part of this specification.

This invention relates toan improved type y of an unloading device adapted to permit oil to be unloaded from a tank car or other container by means of counterbalanced pivotally supported pipes adapted, when unlocked, to be pulled .downwardly into an unloading position by means of chains to permit suction pipes permanently connected by swing joints to saidrcounter-balanced pipes to be conveniently inserted into an oil tank which is to be emptied.

It is an object of this invention to provide an improved type of an oil unloading` device. It is alsov an object of the invention to provide an oil unloading rack lwith means by one man to connect the suction pipe with a tank to be emptied.- i

It is an important object of this invention to provide an unloading rack ofy simple and improved construction adapted to be readily connected with a tank car or liquid container to permit unloading of the liquid from the container.

Other and'fu'rther important 'obj ects-of this invention will be apparent from the disclosures in the drawings and specification.v

The invention (in al preferred'form) is illustrated on the drawings and hereinafter more fully described.

O n the drawings: Figure 1 is a side elevation of an unloading rack in unlocked position connected with a tank car to be unloaded. y Figure 2 is a rear elevation oftheunloading rack in locked position. j

Figure 8 is an enlarged fragmentary detailed section taken on line 3,-.-3 of yFigure j 1 with parts shownin elevation.

Figure 4 is an enlarged detail section taken on line A4.of Figure 2.

Figure 5 is an enlarged fragmentary detail section taken' online 5-'5 of Figure 2.

' As shown on the drawings:

lThe reference. numeral y1 indicates a flat freight car having mountedthereon a tank 2, provided with longitudinal side rails 3 and with a dome 4Q i. i f

The unloading rackembjodyingthe principles of this invention yis mounted on founda.

tion blocks 5 and 6 and comprises two pipe legs or' supporting` pipes 7 the lower ends of which are embedded in thej foundation blocks 5, while theuppen threaded ends of said'legs are` closed by means of` plugs 8.

'.Ihreaded onto theupper endof each leg .7 is apipe cross 9 having ay 'plug10 removably" en'gaged'in'thefrontarinjthereof. Secured inthe rear arm of eachcross'fQ is a horizontal ldischarge pipe 11. having' a quick. closingr valve 12 connected therein. The discharge pipes .11 areconnected with ,storage tanks orother Asuitable containers y"not shown.

Threadedl into the upper arms rvof the crosses i l 9v are tw vupright[frame pipes 13 having single swing joints 14: attached to the upper ends thereof. Connected t0 each swing joint swivel pipe 15 is a pipe cross 16. Each cross 16 has a shorthorizontal pipel? [secured in'one of the arms thereof. '.The adjacent ends of the short pipes 1'( are'connected means of a union 18. constructedl to permit the crosses 16 to V-loe rotated. Each of the short'pipes 17 hasa plug 19 securedin the outer endthereof where it enters its respective cross 16.

-Secured in thelower arm of each'cross 16,"

is a pipe `20 closed,'wherek it enters the cross, by means-of a- Vplug 21. 1 -Attachedon' the lower or outer end of eachy pipe20 iis a counterweight or balance block 22 held in the outer end'of which ya single swing joint `place by set collars 'Secur'edin the last'.` y 'arm of each cross y16'is an outlet pipe'24: on"y 25 is secured. A suction pipe 26 is connected lto each single swing joint 25. lClamped on the outer end of each pipe 24 is a collar 27 to which one end of a chain 28 is attached.

Rigidlyconnected -to the two upright frame pipes 13 is a cross-bar 29 held in place by U-boltsA 30. The ends of the cross-bar 29 are bent at right-angles to atlord ianges 3l and 32. The end of the flange 32 is curled to form an eye 33. Engaged through an opening in the Harige 31 is a ring 34. A locking b ar 35 has one end engaged on the'ring 34 while the other end of said locking barhas an opening 37 therein adapted to permit the eye 33 to project therethrough when the bar 35 is in locking position as illustrated in' Figure 4. A padlock 36 is .provided to engage in the eye 33 to hold the bar locked inv place. Secured to the inner `surface ofthe cross-bar 29 are two pairs of spring clips 33 for receiving and holding the pipes 20 in upright position when the unloading device is not in use.

Rigidly secured to the middle portion of the cross-bar 29 is the upper end of a brace bar 39, the lower end of which is rigidly secured to the foundation block 6.

The operation is as follows: v

.As illustrated in Figure 2, the counterweighted swinging pipes 2 0-24 are engagedin the spring clips 33 and are locked inplace by means of the locking bary 35 andthe padlock 36. To use the unloading` rack for the purpose of removing oil from the "tank cary `l--2, the tank car is pulled into position adjacent the unloading rack as shown in Figure'l, The padlock 36 is then unlocked by means' of a key and removed from the, cross-bar eye 33. The locking barh is then removed from engagement with` thel eye and is suspended by the ring 34 as illustrated in Figure l. i

v@ne man can easily operate the device by pulling one of the chains 28. The pi e 2O is forced out of engagement with tie spring'clips 38,'fthereby permitting the pipe 24 to swing downwardly into the position shown in Figure vl. As the pipe 24 moves downwardly, the suction pipe 26, which is pivotally connected therewith by means of .the swingjoint |25, swings into position over thetankdome 4 and is lowered into the tank2. To hold the suction pipe 26 in place' during an unloading operation against the action of the counter-balance 22, the

' chain l28is ysecured to the tank rail 3. lf

desired, bothsuction` pipes 2 6y may be pulled downwardlyv into unloading position and engaged the tank `2 through the tank dome 4.

. 'j Oil-from thel car tank 2 is drawn upwardly by ysuction through the suction pipes 26 throughthe'crosses 16 and the swing joints and the loutlet pipes 24 and tlows 14 downwardly through the frame pipes 13 and the crosses 9 into the discharge pipes 1l. The oil is permitted to then flow through the quick closing valves l2 and is discharged from the pipes l1 into a reservoir or storage tank connected with said pipes 1l.

When the tank car has been emptied, the chains 23 are detached from the tank rails 3. The eounterweights 22 drop by gravity, thereby causing the pipes 24 to swing upwardly drawing the suction pipes 26 upwardly out of the tank dome 4 back into normal position. The swing joints 25 permit the suction arms 26 to swing back into normal position while the pipes 20l tall into a vertical position and engage in the spring clips 38 which serve to hold the pipes 24` 20'in vertical position. The locking bar is vthen engaged over the eye 33 and the padstruction may be varied 'through a wide range without departing from the principles of thisinvention, and vI'therefore do not purpose limiting the patent granted, otherwise than necessitated by the prior art.

l claim as my invention:
